'REPEATING lAIR GUN YApplicatic'm filed. December 10,1928. Serial No. 324,860." Y

This invention relates to a'repeatingair un. g The invention is concerned principally with a toy air gun which is in the nature of the so-called pop-gun type; this type being onev designed to propel a moreor less harmless pellet as for example through the medium of compressed air. The invention is centered around a mechanism arranged to `feed the pellets one byone and place them in the barrel, and this mechanism is operably associated withthe cocking mechanism for the gun, so that upon cocking of the gun a pellet is placed in the barrel to be projected.

Ordinarily, such a `gun has a barrel with a plunger and the pellet is placed into the end of the barrel and as the plunger moves under spring action in the barrel the air between the plunger and pellet is compressed v until the pelletV is forcibly ejected. Accordingly, the mechanism contemplated by this invention is arranged to carry a plurality of pellets, and the pellets are fed one by one, as the gun is cocked and fired, into a position forward ofthe barrel and then itis urged into thebarrel with the required force to make it suiciently fastfor the purpose.

In the drawings: f

the next step in the pellet feeding operation; and Fig. 7`illustrating the. final position of vThe gun is constituted of the nsualstock 1, barrel 2, and trigger. AvWithin thebarv rel is a piston or plunger 4 mountedv upona Vrod A pump handleis shown at 6, and

this handle is connected with .the rod 5. The handle 6 isi-reciprocable on the barrel and when it is-retracted by the operator the plunger is retracted, as indicated in Fig. 4, thus compressing'theusual spring 4a; and the plngerA is held retracted by suitable'trigger mechanism which is'released upon actuation of the trigger 3 by the operator. This gun construction forms no part of the yinvention, as the plunger, spring operation and trigger construction are all well knownV in the'art and anyone of'variou's forms may be-selected. Y" i With this type of gun, the plunger, when released, will forcibly discharge a pellet whichis in the barrel, Vand repeating or feeding mechanism,fno'wfto1 be described, feeds a `pelletr into the barrelupon actuation of the pump handle.v .The pump handle, 'in the present instance, is 'secured to sheet metal flange members 7 and 8 whichV alsoreciprocate withfthe handle. The members 8 are each provided with a slot 9 and in these. Vslots are disposed. the ends of a U-shaped piece of wire 10V (Fig. 2) the ends of the wire being shown at .11.

Mounted upon the end of the gun, Vpreferably near the end vof the barrel, `is a tubular magazinel 'having an enlarged opening 14 through which the pellets may be placed in the magazine. A spring pressed plunger or follower device 15 lies in this magazine and it has a handle'4 part 16 which projects through a slot'ul?` inthe magazine. The spring 1,8 urges the plunger 15 forward, but the plungercan be "retracted manually by a ypull on the handle piece 16. By referring to Fig. 2is will be noted that by retracting the plunger to a point to the right of the opening 14, that a plurality of pellets can be placed within the maga-Zine whereupon the release of the plunger permits the same, under the action of the spring 18, to urge all the pellets forwardly in the magazine. The plunger may be formed by a single length of wire suitably shaped to form the plunger part 15, the handle 16, and rearwardly extending guide rods 19. These guide rods extend through the apertured wall 20 and serve to guide the plunger inV its movement.

Thus a plurality of pellets, as referenced 21, and as shown in Fig. 4, are constantly urged forward by the plunger 15. Mechanism is provided at the end of the gun for feeding the end pellet to the barrel and this mechanism will be best understood by reference to views 4 to 7.

At the end of the gun there is a supporting member 22 provided with a slot 23 which, for a portion of its length, is angularly disposed, as shown, and which has a horizontal part 24. This supporting member 22 may be of sheet metal fixably secured to the end of the barrel and magazine, and the slot 23 is in reality two slots, one on each side of the housing shaped sheet metal which forms the support. The bight po;- tion of the U-shaped wire 10 lies in this groove, as shown at 25. i

There is a combined stop and feeding member mounted in the support 22 for feeding the pellets out of the magazine. This member is referenced 26 and it is pivoted on a cross pin 27. The stop member 26 has an elongated slot 28 in which the. cross pin 27 lits, thus to permit of some relative movement between the feeding member and the cross pin for a purpose which will presently be brought out. A spring 29 in the nature of a tl-shaped wire with its ends coiled around the coil spring engages the feeding member 26 and holds it in the position shown in Fig. 4. The bight portion of this spring, as shown at 36, engages the feeding member 26. There is a stationary abutment fixed in the support 22, as referenced 31, and this abutment is slotted centrally as at 32 for receiving the feeding member 26.

The operation of this automatically acting feeding device will also be best understood by considering the following description with Figs. 4, 5, 6, and 7. In Fig. 4 the parts are shown in normal position with a-number of pellets in the magazine, and the gun is ready to be cocked by a pull ofthe plunger' rearwardly to the dotted position shown. This is accomplished 'by pulling the pump handle 6 rearwardly. lVhen this Vis done, the ends 11 of the U-shaped wire 10 are engaged by the ends of the slots 9 whereupon this wire is retracted with tl e pump handle. The bight portion 25 of the wire will now be caused to travel from its position shown in Fig. 4 to the position shown in Fig. 7 and in this movement it slides up the cam shaped part of the slot 23 and it also performs several operations on the other mechanism.

The bight portion 25 first comes into contact with one end of the stop 26, and upon continued movement it rocks the stop 26 after the manner shown in Fig. 5. This rocking movement takes place upon the cross pin 2'.7 and against the action of the spring 29. Tt will be understood that the stopmember 26 lies in a slot 31a in the housing 22.Y One end of the stop, therefore, is moved out of the way of the pellets whereupon the pellets are urged forwardly by the spring 18 until the forward pellets are stopped by the fixed abutment 31.- The forwardmost pellet is now lying over the stop member 26 (Fig. 5).

UponV further Vmovement, the bight portion 25 moves to the dotted line position of Fig. 6, thus freeing the stop member 26, whereupon the same is snapped back to its normal position by the spring 29. In other words, as the bight portion assumes a position approximating that shown by the dotted line in Fig. 6, the stop 26 is snapped from its dotted line position back to its full line position. Upon referring to Fig. 2 it will be observed that the stop member has outwardly extending ears 32a which strike the metal around the slot 31a and prevent the stop member from moving past its normal position. The fixed stop 31 may also aid in this respect.

The forwardmost pellet has, by' this movement, been moved. upwardly from the position shown in Fig. 5 to that of Fig. 6, so that it now lies approximating forwardly of the open end of the barrel. The coclring movement of the pump handle is not yet completed, and further movement causes the bight portion 25 to engage this raised pellet so that the pellet is forced into the end of the barrel as shown in Fig. 7. The end of the barrel may advantageously be swedg :l out a bit as at 33, so that the pellet is nusher in and the material thereof is more or less compressed in the end of the barrel.

p At this time, the gun has been cocked by movement of the pump handle to its rearmost position whereupon the next movement of the operator is to again push the pump handle forwardly. This` movement of the pump handle is a similar movement to that of an ordinary pump ,action gun. This moves the wire 10 and its bight portion 25 back to position shown-in Fig. 4. However, it will be notedby reference to Fig. 6, and also F ig. 4, that the stop member more orV less blocks the path of the bight portion. However, by reason of the provision of the elongatedslot 28, the bight portion engages the upper part of the stop member when the stop member is in the position ofthe full lines as shown in Fig. 7, and then urges the stop member down to the dotted Vline position of thisigure. In other words, the stop member is pushed down with the cross )in 27 sliding in the elongated opening 2S.

n this movement the stop member has sortl ofA a pivotal movement around the ears v32av l is released and the airV is compressed between the piston and the pellet which is frictionally engaged in the end of the rbarrel and when suhicient pressure is obtained, the. pellet is forceably expelled in the .well known manner. Y

It will be noted that someV movement of the'p'umphandle 6 is permitted without vmovement of the wire l() which is the connecting link with the automatic feed mechanism. The normalposition of the parts are about that as shown in Fig. l with 4the ends l1 of the wire positioned near the rear of the slots 9. The handle 6 is of course pulled back quickly with a jerk. Quite some resistance must be overcome in pulling the bight portion 25 Vfrom its position in Fig. l through the position of Fig. 5 and to the position of Fig. 6, because the bight portion mustby a'cam action swing the stop member 26 against the spring 29. However, by reason of the slots` 9, the handle as it is moved back quickly with a jerk, obtains a considerable momentum "as also does the arm of the operator, so that the ends ll of the wire are quickly jerked whenA they engage the ends `of the slots 9. In other words the cooking movement is well under way by the time there is a pull upon wire l0 so that the bight portion 25 is readily snapped past the stop atfeed member 26, andthe force required to perform this is not appreciably noticeable. The point which we are trying to make here, is thatit would be more difficult to effect the initial movement of pumping action if the initial movement also actuated the stop and feed member 26. As it is however, the feeding mechanism is not actuated until the pumping movement of the varm of the operator is well under way and the jerk and pull of the wire 10 is preciably noticeable.
